Pneumatic Valve 5-Way Corner Nailer Tabletop 8-Cylinder – NN33 HBQD
The pneumatic valve 5-way corner nailer tabletop 8-cylinder NN33 is the central air control valve that manages the main nailer cylinder operation on tabletop and 8-cylinder corner nailers. As an air-piloted (rather than solenoid-controlled) directional valve, it delivers reliable, high-flow control without requiring any electrical connection—making it the standard choice for pneumatic (non-CNC) corner nailer designs.
Air-Piloted Operation
The NN33 pneumatic valve 5-way corner nailer operates by receiving a pilot air signal—typically from the foot pedal valve—that shifts the valve spool between its two positions. When the operator presses the foot pedal, pilot air actuates the NN33, directing main air supply to extend the nailer cylinder and drive the nail. When the pedal is released, the spring return shifts the spool back, retracting the cylinder. This pneumatic-only control loop is robust, simple, and immune to electrical failures.
Connector Specifications
The NN33 uses 3-fen (3/8-inch, approximately 10mm) 8cm straight push-fit connectors at the main working ports (A and B), providing high flow capacity for large cylinder actuation. The pilot port uses a smaller 1-fen (1/8-inch) 4cm elbow connector. The exhaust port uses a 2-fen (1/4-inch) silencer to reduce exhaust noise during high-cycle production. All push-fit connections allow tubing installation and removal without tools.
Compatibility With Corner Nailer Types
The NN33 is specified for tabletop corner nailers and 8-cylinder corner nailer systems. These machines use larger cylinders than smaller desktop nailers, which is why the NN33 uses larger 3/8-inch working port connectors compared to the NN28 solenoid valve’s 1/4-inch ports. Verify your machine’s valve specification before ordering.
HBQD 4A310-10 Quality
HBQD’s 4A310-10 is an industrial-grade pneumatic valve rated for high-cycle operation in woodworking and metalworking machinery. The precision spool-and-body construction provides low hysteresis and consistent response times across millions of cycles, ensuring your corner nailer maintains consistent nail depth and timing throughout its service life.
Related Pneumatic Components
The NN33 works as part of the complete corner nailer pneumatic circuit. Connect it with the pneumatic foot pedal switch (NN11), quick exhaust valve (NN27), and oil-water separator (NN32 or NN35) for a complete, well-maintained pneumatic system. XKY Framing stocks all these compatible components for your convenience.
